The correct option is mammals, like Dall sheep.
What is survivorship curves ?A survivorship curve refers to a graph showing the number or proportion of individuals surviving to each age for a given species or group. There are three types of survivorship curves as follow:
Type I curves depict individuals that have a high probability of surviving to adulthood. For example, large mammals have type 1 survivorship curves, because they have a. low infant mortality and high rates of survival into old age.
Type II curves also called as intermediate type, it depict individuals whose chance of survival is independent of age. For example, most birds have type 2 survivorship curves birds die more or less equally at each interval of their age.
Type III curves depict individuals that mostly die in the early stages of their life. For example, Trees, small mammals, some birds, oysters, shell fish, many insects, oak tree and fishes exhibit type 3 of survivorship curve because in these species mortality rate is high during the early stages of life.
Small plants, like Cleome droserifolia is a herbaceous perennials also typically display Type III survivorship curves, with a very low seedling survival and a low initial life expectancy,
Thus, from above explanation, mammals, like Dall sheep, is the correct option.

Indicate the location and function of the plasma membrane, as well as an analogy of it.
Plasma membrane it's located in the exterior of all cells.
The plasma membrane has several functions: first, it's the barrier between the interior of the cell and the rest of the environment; secondly, it protects the cell and gives it support; it also regulates what substances pass to the interior of the cell.
If the cell was a ballon, the plasma membrane would be the latex and all the air inside would be the cytoplasm.

Did the WES2 station move at a constant speed since 1995?
Answer:
probably not
Explanation:
When a velocity's magnitude and direction do not alter over time, it is said to be constant.
What is meant by Constant speed?Constant speed refers to a speed that remains constant throughout the duration of the motion. Constant speed is demonstrated in our example of using cruise control while driving a car.
When a velocity's magnitude and direction do not alter over time, it is said to be constant. In other words, this occurs when an object's rate of change in location remains constant throughout time.
An object is considered to be moving at a constant speed when it covers the same distance in the same amount of time. When moving at a constant place, an object covers a certain distance in a fixed amount of time. S = dt is a formula that can be used to express the speed.

Define gluconeogenesis and lipogenesis. Under what conditions do they predominantly occur?
The process of producing glucose (sugar) from lipid (fat) or protein breakdown products, as well as from its breakdown products is called gluconeogenesis whereas the creation of fatty acids from nonlipid precursors is known as lipogenesis.
Gluconeogenesis predominantly occurs both in the kidneys and the liver, because phosphoenolpyruvate carboxykinase is inhibited by ADP. As a result, gluconeogenesis is encouraged in cells that are abundant in ATP and biosynthetic precursors.
The liver, adipose tissue, small intestine, kidneys, and mammary glands are the primary sites of lipogenesis. Additionally, it happens in blood lipoproteins and the digestive system. It is a metabolic pathway that is activated by the high availability of carbohydrates and is used to break down extra carbohydrates.

I extracted DNA from strawberry. I had to answer: - Why did the DNA separate to the top after adding the isopropyl alcohol? - Does all of your food have DNA? Explain your reasoning. - Why is it important for scientists to be able to extract DNA? Provide two examples.
1. Isopropanol is a compound used to dissolve lipids and as a dehydrating agent. When mixed with DNA, they compete for water causing the DNA to dehydrate and separating the mixture into two phases.
2. Every living organism contains DNA. This includes plants and animals, and therefore most of the food we eat.
3. DNA contains the hereditary information of all living organisms.
For example, in humans it is important to extract DNA for the identification of diseases, their causes and possible treatments.
In food, DNA extraction can help in the production of transgenic foods.

Look up one prion disease and describe it here. What population does this disease infect? How is it usually transmitted? How common is it? What are the major symptoms? Be sure to cite your sources.
Kuru is a Transmissible spongiform encephalopathy which was formerly common among the Fore people of Papua New Guinea. This disease is caused by a prion, i.e., a protein that can trigger other proteins in the brain to fold abnormally. The abnormally folded proteins in the brain cause neurodegeneration which ultimately lead to death. The main symptom of the Kuru disease is the loss of coordination and control over the muscle movements. The transmission of Kuru was because of a ritual in which Fore people consumed body parts of their family members just after their death. The Fore people stopped to eat human meat in the early 1960s, causing the kuru epidemic to decline dramatically. It is not certainly known if the last kuru victim died in 2005 or 2009.

What are the three laws of mendelian genetics ?Mendelian inheritance is a type of biological inheritance that follows the principles that were initially proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and popularized by William Bateson.
Mendel put out the hypothesis that, in order for reproduction to occur, the inherited components need to partition themselves into reproductive cells. It had come to his attention that permitting hybrid pea plants to self-pollinate would result in offspring that did not resemble their respective parents in appearance.
Law of Dominance is one of Mendel's three proposed laws of inheritance, which also includes Law of Inheritance. The law that enforced segregation. The Principle of Independent Assortment is a Law.

At what level of protein structure do amino acid chains twist and fold?a) Tertiaryb) primary c) secondary d) Quaternary
The primary structure occurs when the protein structure is only a chain of amino acids, with no folds or twists. Therefore, b) is incorrect.
This primary structure then twists folds in itself, creating the structure that's folded and held in shape by hydrogen bonds. That's the secondary structure, and whats is folded in it is the amino acids. Therefore, c) is the correct answer.
The tertiary structure is a three-dimensional structure, shaped by interactions between the R groups of the amino a cids. To form this structure, the entire secondary structure elements (not the amino acids) are folded together. Therefore, a) is also incorrect.
The quaternary structure is a closely pack arrangement of several protein chains, each with its own primary, secondary and tertiary structure. Therefore, d) is wrong as well.

Complimentary base strands- Adenine and guanine, as well as thymine and cytosine, are the complimentary bases in DNA. A nitrogen-containing base, such as guanine, adenine, thymine, or cytosine, a monosaccharide sugar termed deoxyribose, and a phosphate group make up each nucleotide in DNA.
The complimentary bases may unite to form a bond. This aids in holding the DNA molecule's two antiparallel strands together just to form the helix. The complimentary base pairing rule refers to this.
According to Chargaff's criteria, DNA from all cells of all creatures should contain a 1:1 ratio of pyrimidine & purine bases. More specifically, the amounts of guanine and adenine should be equivalent to cytosine and thymine, respectively.
